Hello everybody,
I have tried to send some AT commands to external modem connected to Davinci
board via COM cable. Some commands like "AT","AT+FCLASS=?","AT&Q0V1X0",... work
well, but two commands "ATA" and "ATD" do not work , the modem reponses "ERROR"
message.
ex : when the RING signal detected we send "ATA" command to accept but modem
reponse "ERROR".
pls tell me what problem ?
thanks.
